I completely agree and part of why I want to change it. On my machine my wifi and Ethernet devices sometimes swap as being first in the list and it doesn't seem to like that at all. I don't know if it's because my mgmt IP is localhost or what, but the new mgmt host entry never takes over ownership of the previous hosts.
I'd like to make it more deterministic. Not completely sure what the algorithm should be. I was thinking that I'd sort the interfaces by Mac or name and then look for the non-link local nic. Actually, I can just look for the Mac of the IP set as the cluster.node.IP. Some stupid reason I was thinking that was in the DB, but it's (obviously?) in the db.propeties.
